Major blind with individually movable minor blinds structure

ABSTRACT

A major blind with individually movable minor blinds structure includes a head rail, hanging elements, connection brackets, and blind bodies wherein the head rail has a plurality of T-shaped guide grooves for the accommodation of the hanging elements each made up of a joining head to be mounted to the head rail and a coupling end to be registered with a connected portion of each connection bracket having a receiving groove defining one side for the location of the upper edge of the blind body therein. Therefore, via the hanging elements, each blind body can be horizontally slid to the left or right on the head rail as the user desires. And, via an up/down control unit fixed to the connection bracket, the blind body can also be freely raised or lowered in the collection or expansion operation, achieving more versatile changes as well as more convenient application thereof.

BACKGROUND OF THE INVENTION

The present invention is related to a major blind with individually movable minor blinds structure, including a head rail, hanging elements, connection brackets, and blind bodies wherein each hanging element is made up of a joining head to be mounted to the head rail and a coupling end to be registered with a connected portion of each connection bracket thereby; therefore, via the hanging elements thereof, each blind body mounted to the connection bracket thereof can be horizontally slid to the left or right on the head rail as the user desires. And, via an up/down control unit accommodated at the connection bracket therein, each blind body can be freely raised or lowered in the collection or expansion operation, achieving more versatile changes as well as more convenient application of the present invention.

Please refer to FIG. 1. A conventional major/minor blind structure is made up of a head rail 10 and multiple minor blind bodies 20 wherein the head rail 10 has a plurality of guide grooves 11 defining thereon for the accommodation of hanging elements 21 fixedly attached to the upper edge of each blind body 20 thereof.

However, there are some disadvantages to such conventional blind structure thereof. Most of all, the hanging elements 21 are directly fixed to the upper edge the blind bodies 20 that, as a result, can be simply moved to the left or right along with the hanging elements 21 sliding horizontally on the guide grooves 11 of the head rail 10 thereof. Thus, the blind bodies 20, unable to be raised or lowered in the collection or expansion operation thereof, can only suspend downwards by their own weight, which is not only inconvenient in application but also monotonously dull in display.

SUMMARY OF THE PRESENT INVENTION

It is, therefore, the primary purpose of the present invention to provide a major blind with individually movable minor blinds structure, including a head rail, hanging elements, connection brackets, and blind bodies wherein each hanging element is made up of a joining head to be mounted to the head rail and a coupling end to be registered with a connected portion of each connection bracket thereby. Therefore, via the hanging elements thereof, each blind body mounted to the connection bracket thereof can be horizontally slid to the left or right on the head rail as the user desires. Besides, via an up/down control unit fixed at the connection bracket therein, the blind body can also be freely raised or lowered in the collection or expansion operation, achieving more versatile changes as well as more convenient application of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 2 showing an exploded perspective view of the present invention. The present invention is related to a major blind with individually movable minor blinds structure, including a head rail 30 equipped with a plurality of T-shaped guide grooves 31 defining thereon for the accommodation of a plurality of hanging elements 40 each made up of a T-shaped joining head 41 extending at the top thereof and a coupling end 42 with a coupling section 421 (made in a rod-like or screw-threaded form) disposed at the bottom thereof to be reciprocally secured to a locked section 511 (made in a thru-hole or screw hole) disposed at a connected portion 51 of a connection bracket 50. An up/down control unit 60 (such as a pulley seat, a spring-loaded roller set, or a beaded-type roller set, etc.) is fixed to an appropriate position of each connection bracket 50 to control the collection and expansion of a blind body 70 thereby. And a receiving groove 52 is provided defining one side of the connection bracket 50 therein, permitting the upper edge of the blind body 70 fixedly attached to a positioning element 53 (like a positioning plate) to be mounted therein in limiting location thereby.

Please refer to FIGS. 3, 4 showing assembled perspective views of the present invention in application (accompanied by FIG. 5). In assembly, multiple hanging elements 40 are sequentially engaged with the connection bracket 50, each via the coupling section 421 of the coupling end 42 thereof securely fixed to the locked section 511 of the connected portion 51 thereof. Then, the joining heads 41 of the multiple hanging elements 40 are sequentially led into the guide grooves 31 and accommodated therein to mount the hanging elements 40 to the head rail 30 respectively. And via the hanging elements 40 thereof, each connection bracket 50 with the blind body 70 mounted thereto can be horizontally slid on the guide groove 31 so as to synchronically move the minor blind body 70 to the left or right therewith as the user desires. Besides, via the up/down control unit 60 thereof fixed at the connection bracket 50 therein, each blind body 70 suspending downwards from the connection bracket 50 can also be freely raised or lowered in collection or expansion operation thereof. Therefore, the present invention can be variously changed to offer versatile visual effects as a whole and avoid the disadvantages of the dull and monotonous conventional blind structure, achieving multiple functions as well as more convenient application thereof.

Please refer to FIG. 6. The positioning element 53 accommodated at the connection bracket 50 therein can also be made into a positioning linkage device and appropriately fixed to both lateral edges of one side of the connection bracket 50 for the attachment of the blind body 70 thereto. And the joining heads 41 extending at the upper section of the hanging elements 40 thereof can horizontally slide on the guide grooves 31 of the head rail 30 to synchronically actuate the movement of the connection brackets 50 and, thus, the blind bodies 70 therewith. Meanwhile, via the up/down control unit 60 thereof, each blind body 70 mounted at the connection bracket 50 can also be freely rolled up or down in collection or expansion operation thereof.

Please refer to FIG. 7 showing another embodiment of the present invention. The hanging element 40 and the connection bracket 50 thereof can also be securely linked via an assembly fitting 80 made up of a fixed end 81 defined by a fixed section 811 (made in a thru-hole or screw hole), and a fixing end 82 equipped with a fixing section 821 (made in a rod-like or screw-threaded form) to be respectively engaged with the coupling section 421 of the hanging element 40 and the locked section 511 of the connected portion 51 thereof so as to provide more stable and securer connection of the hanging element 40 and the connection bracket 50 thereby.

Please refer to FIG. 8 showing a third embodiment of the present invention (accompanied by FIG. 9). The joining head 41 of the hanging element 40 can also be made in a hook-like shape to be mounted onto one of multiple hanging rods 91 disposed at a head rail 90 thereof.

Please refer to FIG. 10. The hanging element 40 equipped with the hooked-like joining head 41 and the connection bracket 50 thereof can be respectively coupled with the assembly fitting 80 with the coupling section 421 thereof engaged with the fixed section 811 of the fixed end 81 and the locked section 511 thereof secured to the fixing section 821 of the fixing end 82 thereof so as to provide more stable and securer connection thereby.

Furthermore, the blind body 70 can be made into various types of blinds such as the Roman blind as shown in FIGS. 2, 3, the hobbled Roman shade as shown in FIG. 4, and the spring roller blind as shown in FIG. 6.

Please refer to FIG. 11. The present invention can also include a Venetian blind body 70′ directly attached to the underside of a connection bracket 50′ having an up/down control unit 60′ mounted at one lateral end thereon, and connected portions 51′ each defined by a locked section 511′ (like a thru-hole or screw hole) disposed at the upper edge thereon.
